- UFC (@ufc) August 12, 2014Jones (20-1) was scheduled to fight Cormier (15-0) at UFC 178 on Sept. 27 in Las Vegas in the mixed martial arts promotion's most anticipated event of the fall.

Instead, Jones and Cormier will headline UFC 182, the promotion's traditional year-end show in Las Vegas.

Jones is widely considered the top pound-for-pound fighter in MMA, while Cormier is an undefeated former Olympic wrestler. They generated major publicity last week for their bout when they scuffled during a promotional event in the MGM Grand casino lobby.

Johnson (20-2-1) will seek his fifth UFC title defense. He scored a dominant decision victory against Ali Bagautinov at UFC 174. Fighting out of Kirkland, Washington, Johnson is on a six-fight win streak.

The Johnson-Cariaso bout originally was scheduled for Aug. 30 in Sacramento, California.
